Hello Gang,

I was wondering if anyone has fooled around with processing the data from the Weatronics receiver? I have several that include the GPS data.

So, you should be able to process the saved files X,Y,Z co-ordinates, speed information to generate g-load data on the plane. I often wondered how much force we place on our airframes. Using the receiver data, you should be able to calculate the G-loads on the plane.

How about processing the position and current information from the servos? This could, if done right, tell you whether the servo you have installed is adequate for the task or under-sized. It could also maybe tell you whether the mechanical set-up is stressing the servos. This could be valuable from a safety point of view.

Just a few thoughts,

I think the G force calculation would be hard to do and not much use due to various inaccuracies. My Wea GPS is rather poor, turns have the shapes of hexagons instead of circles, speed suddenly varies up and down by 100mph in a second and it regularly shows the model doing circuits and flypasts tens of yards behind the pits! So my experience of the Wea GPS data is that it is totally unreliable for doing any precise work. On top of that you have the general GPS problem that height data is much less accurate than lat/long data, so using it to calculate G in a loop will be poor even if your GPS unit is working well.

I carry an Eagle tree low G sensor in my jets, in stand alone mode it records and displays the highest G level encountered in the flight, so it’s not as good as G per each manoeuvre but at least I get an idea of the maximum stress being put on the aircraft. http://www.eagletreesystems.com/Stan...standalone.htm
